How can i find the list of accredited Testing Laboratory For Fire Resistance Test for doors.Cost is so important for me :confused: so I need to compare the tests cost.
Thanks for your help.

I would start with UL (Underwriters Laboratories)
Perhaps they have a list of test labs that they work with in UL marking.

Maybe NFPA (National Fire Protection Association) as well.

OSHA maintains a list Nationally Recognized Test Labs

Scott is on the right track. I noticed that you are from Turkey and the authority you need to approach should be your national fire fighting department or product testing and standards department.

If you are in my country I can even get you a product development grant to defray the cost of such test. Check if such are available in your country.

Here is a link to North American Fire Testing Laboratories Consortium (http://www.naftl.org/index.cfm) that may help you.
